Thesecond recovering component 82 can be disposed between thesecond housing 76 and the second button 78, or between thesecond housing 76 and thesecond lock 80. - In the embodiment, the second button 78 can be rotatably disposed inside the
second housing 76. A part of the second button 78 can be protruded from thesecond housing 76, and the other part of the second button 78 can be accommodated inside thesecond housing 76 to abut against thesecond lock 80 in a detachable manner or in an undetachable manner. If the external force is applied to the second button 78, the second button 78 can be rotated in the counterclockwise direction to drive and disengage thesecond lock 80 from thehole 30 on thelower leg tube 20, and then thelower leg tube 20 can be slid relative to theupper leg tube 18, as conditions shown inFIG. 15 toFIG. 16 . If the external force is removed, a resilient recovering force of thesecond recovering component 82 can rotate the second button 78 in the clockwise direction, and thesecond lock 80 can be driven to pierce through theupper leg tube 18 and engage with thehole 30 on thelower leg tube 20; thus, thelower leg tube 20 cannot be slid relative to theupper leg tube 18, as conditions shown inFIG. 16 toFIG. 15 . - In some possible embodiments, the resilient recovering force of the
second recovering component 82 may rotate thesecond lock 80 for engaging thesecond lock 80 with thehole 30 on thelower leg tube 20. Besides, the second button 78 and thesecond lock 80 may be set as linear slide design; for example, the second button 78 may be pushed or pulled to move in a straight direction, and thesecond lock 80 may be actuated by the second button 78 to move in another straight direction similar to or different from the foresaid straight direction. - The
second lock 80 of thesecond latch 26 can have a specifically inclined guidingstructure 84 disposed on a front end of thesecond lock 80. When thesecond lock 80 is inserted into thehole 30 on thelower leg tube 20, theinclined guiding structure 84 can be pressed by the downwardly movedlower leg tube 20 to disengage thesecond lock 80 from thehole 30 on thelower leg tube 20. Thestability leg 16 can be stretched by at least two ways. One way is pulling down on thelower leg tube 20; thesecond lock 80 can be pressed by thelower leg tube 20 to disengage from thelower leg tube 20, and then thelower leg tube 20 can be downward moved relative to theupper leg tube 18. Another way is pressing the second button 78; the second button 78 can be rotated or shifted to actuate disengagement of thesecond lock 80 and thelower leg tube 20. - Please refer to
FIG. 17 toFIG. 20 .FIG. 17 is a side view of a bottom of thestability leg 16 in a non-contact mode according to the embodiment of the present invention.FIG. 18 is a front view of thestability leg 16 in the non-contact mode according to the embodiment of the present invention.FIG. 19 is a side view of the bottom of thestability leg 16 in a contact mode according to the embodiment of the present invention.FIG. 20 is a front view of thestability leg 16 in the contact mode according to the embodiment of the present invention. - The
stability leg 16 can further include afoot housing 86 and anindicator 88. Thefoot housing 86 can be disposed on a bottom of thelower leg tube 20, and have awindow 90 formed on a front surface of thefoot housing 86. Theindicator 88 can include amain body 92, afirst indication mark 94, asecond indication mark 96 and anelastic component 98. Themain body 92 can be movably disposed inside thefoot housing 86. Thefirst indication mark 94 and thesecond indication mark 96 can be disposed on respective positions on themain body 92. Theelastic component 98 can be disposed between themain body 92 and thefoot housing 86. - The
main body 92 can be disposed inside thefoot housing 86 in a rotatable manner or in a slidable manner. In the embodiment, themain body 92 is rotatable inside thefoot housing 86. Themain body 92 can have afirst end 921 and asecond end 922 opposite to each other. Thefirst end 921 can be protruded from or accommodated inside a bottom of thefoot housing 86 according to motion of themain body 92. Thefirst indication mark 94 can be a red color mark formed on a lower position on thesecond end 922 of themain body 92, and thesecond indication mark 96 can be a green color mark formed on an upper position on thesecond end 922 of theman body 92. - If the
stability leg 16 is suspended and does not abut against the vehicle floor, thefirst end 921 can be protruded from the bottom of thefoot housing 86, and thesecond end 922 can be located at high position to align thefirst indication mark 94 with thewindow 90, as shown inFIG. 17 andFIG. 18 ; the exposed red color mark represents theinfant car seat 10 is in an incorrect installed mode. If thestability leg 16 is lowered to abut against the vehicle floor, thefirst end 921 can be rotated in the counterclockwise direction by pressure to accommodate inside the bottom of thefoot housing 86, and thesecond end 922 can be moved downward to align thesecond indication mark 96 with thewindow 90, as shown inFIG. 19 andFIG. 20 ; the exposed green color mark represents theinfant car seat 10 is in a correct installed mode. When thestability leg 16 is lifted, a resilient recovering force of theelastic component 98 can rotate themain body 92 in the clockwise direction to align thefirst indication mark 94 with thewindow 90. - As shown in
FIG. 4 andFIG. 11 toFIG. 16 , an amount of theopening 28 can be less than an amount of thehole 30, so thefirst latch 24 can be used as gross adjustment, and thesecond latch 26 can be used as fine adjustment. Relative motion between thefirst latch 24 and theupper leg tube 18 can be executed for a start to rapidly extend theindicator 88 close to the vehicle floor; then, relative motion between thesecond latch 26 and thelower leg tube 20 can be executed to abut theindicator 88 against the vehicle floor tightly. When theinfant car seat 10 is folded, the gross adjustment and the fine adjustment can be executed simultaneously or individually in accordance with an operation custom. - In the embodiment of the present invention, the stability leg has the upper leg tube and the lower leg tube slidably assembled with each other. The first latch is used to constrain the relative movement between the upper leg tube and the rotary member, and the second latch is used to constrain the relative movement between the upper leg tube and the lower leg tube. The gross adjustment of the stability leg can lock the upper leg tube in an upper position for installing the infant car seat in a shorter and center vehicle seat, and further lock the upper leg tube in a lower position for installing the infant car seat in a taller and outboard vehicle seat; the fine adjustment of the stability leg can lock the lower leg tube via one of the holes on the lower leg tube to change an extended length of the stability leg.
- Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
